Nebulizer system for a motor vehicle

ABSTRACT

A nebulizer system for a motor vehicle may include a tank for a liquid, a nebulizer chamber, and a filter system capable of filtering the liquid contained in the tank for the liquid before it passes into the nebulizer chamber. The nebulizer chamber may have a nebulizer nozzle provided with an acoustic wave output device such that the liquid from the tank forms a mist of droplets of the liquid. The mist is intended to pass into a passenger compartment of the motor vehicle. Additionally, the nebulizer system may have an input module for air. The inlet module may have an air injection volute capable of channeling the air in the direction of the internal volume of the nebulizer chamber.

The invention concerns a nebulizer system for a motor vehicle.

More particularly, it concerns a nebulizer system comprising at leastone tank for a liquid, a nebulizer enclosure, the nebulizer enclosurecomprising a nebulizer nozzle provided with a device for emittingacoustic waves transmitted into the liquid and configured such that thesurface of the liquid from the tank generates a mist of droplets of theliquid, the mist being intended to enter a passenger compartment of themotor vehicle, and a filter system capable of filtering the liquidcontained in the tank before it passes into the nebulizer enclosure.

Such a nebulizer system can be used to cool and/or humidify an airstream in which the mist of droplets is nebulized.

In a passenger compartment of a motor vehicle, it is not unusual forusers of the vehicle to suffer from the heat in the passengercompartment, in particular the rear passengers, who are positionedfurthest away from the air vents connected with a ventilation, heatingand/or air conditioning device of the vehicle.

As a result, it is advantageous to use a nebulizer system, because themist of droplets quickly cools the air of the passenger compartment,providing an instant cold sensation.

However, existing systems do not allow a uniform air speed around thenebulizer nozzle, which reduces the quantity of mist sent to thepassenger compartment of the motor vehicle.

The invention aims to improve the situation.

For this purpose, it proposes a nebulizer system as previously describedin which the nebulizer system comprises an air inlet module, this airinlet module comprising at least one air injection blower housingcapable of channeling the air towards the internal volume of thenebulizer enclosure.

Other features and advantages of the invention will become clearer uponreading the description that follows. This is purely illustrative andshould be read in view of the appended drawings in which:

FIG. 3 shows a perspective view of a liquid tank of a nebulizer systemaccording to the present invention, and,

FIG. 4 shows a front view of the liquid tank of a nebulizer system ofFIG. 3 .

The invention concerns a nebulizer system 10 comprising at least onetank 12 for a liquid, a nebulizer enclosure 14 and a filter system 16.

The liquid contained in the tank can be water, for example.

The filter system 16 is capable of filtering the liquid contained in thetank 12 for the latter before it passes into the nebulizer enclosure 14.The filter system 16 is capable of filtering the liquid contained in thetank 12 and can, for example, form an antibacterial barrier.

In this example, the filter system 16 is arranged in fluid communicationbetween the tank 12 for the liquid and the nebulizer enclosure 14.

The nebulizer enclosure 14 is produced, in this instance, in the form ofan elongate hollow body extending along a longitudinal axis A.

In the embodiment shown in the figures, the longitudinal axis A ishorizontal.

The nebulizer enclosure 14 comprises at least two parts arranged, inthis instance, one after the other in the direction of the longitudinalaxis A, i.e. a nebulizer chamber 20 and a nebulizer tube 18. In otherwords, the nebulizer chamber 20 and the nebulizer tube 18 are coaxial.

In the embodiment shown here, the nebulizer chamber 20 has a largercross section than the nebulizer tube 18. In this example, the nebulizertube 18 extends at least partially into the nebulizer chamber 20.

In the embodiment shown here, the nebulizer tube 18 and the nebulizerchamber 20 are cylindrical with a generally circular cross section,concentric, and both extend along the longitudinal axis, which is inthis instance horizontal.

The nebulizer enclosure 14 comprises a nebulizer nozzle 22 provided witha device for emitting acoustic waves transmitted into the liquidconfigured such that the surface of the liquid from the tank 12 for thelatter generates a mist of droplets of the liquid, this mist beingintended to enter a passenger compartment of the motor vehicle.

The longitudinal axis of the nebulizer nozzle 22 is substantiallyparallel to the longitudinal axis A of the nebulizer enclosure 14, i.e.it is horizontal in the embodiment of the invention shown here.

The nebulizer nozzle 22 is arranged at least partially inside thenebulizer enclosure 14 and, in particular, in the nebulizer chamber 20.The nebulizer nozzle 22 can be inserted through an opening (not shownhere) with, as required, insertion of a seal (also not shown here).

The nebulizer nozzle 22 comprises a lateral wall delimiting an internalvolume capable of containing the liquid to be nebulized. The inner crosssection of this lateral wall gradually narrows towards an outlet portfor the liquid 24. The gradual narrowing makes it possible to form anacoustic wave concentrator.

A piezoelectric (ceramic) element is arranged opposite the outlet port24 for the liquid.

The piezoelectric element is capable of emitting acoustic waves into theliquid to be sprayed, which makes it possible to generate a mist ofdroplets of liquid when the nebulizer nozzle 22 is filled by the latterand when the piezoelectric element emits acoustic waves of a suitablefrequency and intensity. Preferably, the piezoelectric element can emitultrasound at a frequency of between 1 MHz and 3 MHz, in particularbetween 1.7 MHz and 2.4 MHz.

The piezoelectric element is, for example, a quartz.

For example, the diameter of the droplets contained in the mist is lessthan 10 μm.

The nebulizer nozzle 22 also comprises at least one inlet port 23 forthe liquid to be nebulized which allows the liquid to be nebulized toenter the internal volume of the nozzle.

In a specific example, a plurality of inlet ports 23 for the liquid, forexample four, are provided around the longitudinal axis of the nebulizernozzle 22, in a zone close to the piezoelectric element.

At least one means for detecting a lack of liquid can also be provided.The means for detecting a lack of liquid can, for example, be a levelsensor.

The nebulizer system 10 further comprises an air inlet module 26, thisair inlet module 26 being secured to the nebulizer enclosure 14. The airinlet module 26 can be secured by any servo control means known to aperson skilled in the art.

In this example, the air inlet module 26 is attached, in particular in aremovable manner, to the nebulizer chamber 20.

The air inlet module 26 comprises at least one support for an air-movingfan.

The air inlet module 26 further comprises an air filter 28 which can,for example, be arranged at the inlet of the fan, and, for example,arranged on the latter. The air filter 28 can, for example, comprisepores with a minimum dimension of 0.2 μm.

In an example not shown here, the nebulizer system 10 can comprise adeflector capable of directing the air towards the air inlet module 26and therefore towards the nebulizer system 10.

A grating may also be provided over the air filter 28, capable ofprotecting this filter.

It can be seen that the fan and the air filter 28 are, in this instance,arranged in a direction of extension perpendicular to the longitudinalaxis A of the nebulizer enclosure 14 and on one side of the nebulizersystem 10. In this instance, the fan and the air filter 28 are arrangedclose to an outlet pipe for the mist 34 that is described below. Such anarrangement is advantageous in that it is compact and further helpsprotect the filter in the event of falling elements. Indeed, in theevent of falling elements, the latter will fall onto the frame of theair filter 28 and not onto the filtering medium of the latter.

An embodiment not shown here proposes that either the fan or the airfilter 28 are arranged in a direction of extension perpendicular to thelongitudinal axis A of the nebulizer enclosure 14 and on one side of thenebulizer system 10.

To this end, the tank 12 for the liquid comprises an indentation or ashape allowing the air inlet module 26 and, in particular, the fanand/or the air filter 28, to be at least partially accommodated.

According to the invention, the air inlet module 26 also comprises anair injection blower housing 30 that allows the air from the fan to bechanneled towards the internal volume of the nebulizer enclosure 14. Inparticular, the air injection blower housing 30 allows the air to beswirled around the nebulizer tube 18 while directing this air towardsand around the nebulizer nozzle 22.

One embodiment proposes that the air injection blower housing 30 issemi-circular, viewed from the front.

The air injection blower housing 30 is suitable for being appliedagainst the nebulizer enclosure 14 and, in particular, against thenebulizer chamber 20 at an opening (not shown here) referred to as theair inlet opening, with sealing means that are not shown here insertedas required.

The air injection blower housing 30 can also be in the shape of a spiralwinding around the nebulizer enclosure 14, which helps achieve theeffect of rotating the air in a spiral around the nebulizer enclosure 14so as to supply it in an even more effective manner. Such a shape helpsproduce an air stream of uniform speed around the nebulizer nozzle 22,at least in the direction of the longitudinal axis A.

In the example shown here, the nebulizer system 10 comprises redirectionmeans 32, which allow the direction of flow of the air from the airinjection blower housing 30 to be modified towards the vicinity of thenebulizer nozzle 22. In the example shown here, such means make itpossible to redirect the air around the nebulizer nozzle and parallel tothe jet of liquid exiting the latter.

In other words, and as shown in FIG. 2 , the air enters the nebulizersystem 10 via the air inlet module 26 and, in particular, via the airfilter 28, then passes through the fan. In this phase of its journey,the air circulates perpendicular to the longitudinal axis A of thenebulizer enclosure 14.

Next, the air arrives in the injection blower housing 30 before enteringthe nebulizer enclosure 14 at the nebulizer chamber 20. The injectionblower housing 30 allows the air to be introduced into the nebulizerchamber 20 once more perpendicular to the longitudinal axis A of thenebulizer enclosure 14.

The air introduced into the nebulizer chamber 20 is then directedparallel to the longitudinal axis A of the nebulizer enclosure 14 andcounter-current to the direction taken by the liquid nebulized by thenebulizer nozzle 22, until it comes up against the redirection means 32.

The redirection means 32 then direct the air in a manner substantiallyparallel (co-current) to the direction taken by the liquid nebulized inthe nebulizer nozzle 22.

The air and the nebulized liquid mix in the nebulizer enclosure 14, inparticular in the nebulizer chamber 20. Therefore, the air helps expelthe mist from the nebulizer system 10.

The nebulizer system 10 further comprises at least one outlet pipe forthe mist 34 or 36.

In this instance, the outlet pipe for the mist 34 or 36 is arranged atthe nebulizer enclosure 14 and, in particular, in the nebulizer tube 18part of the latter, and in its distal part of the nebulizer nozzle 22.

In the embodiments of the invention shown here, the nebulizer system 10comprises two outlet pipes for the mist 34 and 36.

Each of the outlet pipes for the mist 34 and 36 extends here to an endport in fluid communication with at least one air vent 48 of the motorvehicle and thus the passenger compartment of this same vehicle.

In the embodiment shown here, as an example, each of the outlet pipesfor the mist 34 and 36 diverges laterally from the nebulizer enclosure14 at an angle of approximately 55° to the longitudinal axis A and tothe jet of liquid exiting the nebulizer nozzle 22. The general extensionaxes of the two outlet pipes for the mist 34 and 36 together form anangle of approximately 110° to 130°.

At least one of the outlet pipes for the mist 34 or 36 may be providedwith a flap allowing the flow of mist to be controlled.

The nebulizer tube 18 is extended after it joins the outlet pipes forthe mist 34 and 36 by a tube referred to as the discharge tube for thenon-nebulized liquid 38.

The discharge tube for the non-nebulized liquid 38 is intended todischarge the non-nebulized liquid, possibly mixed with a fraction oflarge drops. Large drops should be understood to mean drops with adiameter larger than 10 μm.

The discharge tube for the non-nebulized liquid 38 is extended in thisinstance by an end portion, the passage cross section of whichdecreases, preferably continuously, towards an end port 44.

The end port 44 is, in this instance, placed in communication with afiller pipe 46 of the nebulizer system 10.

The filler pipe 46 of the nebulizer system 10 also comprises an inlet 50through which the nebulizer system 10 is supplied with liquid.

One embodiment proposes that a flared or funnel-shaped end-piece 52 isfitted to the filler pipe 46. The funnel shape helps better direct theliquid towards the tank 12 for the liquid. Moreover, this shape is alsoadvantageous in that it allows different elements to be accommodated,such as a pre-filter.

In an embodiment not shown here, the end-piece 52 comprises a filterreferred to as a pre-filter for the liquid to be nebulized, which allowsparticles of a large diameter to be eliminated from the liquid, inparticular when the tank 12 for the liquid is being filled.

The pre-filter advantageously traps particles with a diameter greaterthan 30 μm and preferably between 50 and 200 μm, so as to trap particlessuch as grains of sand, for example. This pre-filter can be removed inorder to be changed periodically.

The end-piece 52 and the filler pipe 46 are, in this instance, part ofthe filling circuit of the nebulizer system 10.

The nebulizer system 10 according to the invention can be filled withliquid (in particular water) via a hatch that can be accessed by a rearpassenger of the motor vehicle equipped with the nebulizer system 10.

The nebulizer system 10 can also comprise an indicator displaying thefilling level of the tank. One embodiment proposes that the latter isarranged at the central console 100 of the motor vehicle.

The nebulizer system 10 for a motor vehicle comprises, as indicatedabove, a tank 12 for the liquid.

The tank 12 for the liquid is shaped such that at least one wall isinclined relative to a wall situated opposite this inclined wall.

In the embodiment shown here, the tank 12 for the liquid comprises 6faces, at least one face referred to as the bottom face 60, one facereferred to as the top face 62, and four lateral faces. In other words,at least two lateral faces situated opposite each other have differentdimensions and, in particular, different heights.

The bottom face (or wall) 60 is inclined relative to an opposing topface 62 and has a length and a width.

One specific embodiment proposes that the angle of inclination betweenthe inclined bottom face 60 and the opposing top face 62 is preferablybetween 10 and 20°.

In this instance, the angle of inclination between the inclined bottomface 60 and the longitudinal axis A is preferably between 10 and 20°.

The inclined bottom face 60 of the tank 12 for the liquid comprises atleast one retaining means 64 for the filter system 16.

In the embodiments shown here, two retaining means 64 for the filtersystem 16 are provided and are produced in the form of half-ringscapable of gripping the filter system 16 which is, in this instance,produced in a cylindrical shape.

Thus, the inclined bottom face 60 holds the filter system 16 in anorientation that is also inclined. In other words, the filter system 16is arranged in an inclined manner relative to the longitudinal axis A ofthe nebulizer enclosure 14. In yet other words, the filter system 16 isarranged in an inclined manner relative to the opposing top face 30 ofthe tank 12 for the liquid. Such an arrangement is advantageous in thatthere are no water retention points in the nebulizer system 10, whichmakes it easier to drain the nebulizer system 10 according to thepresent invention. Moreover, this arrangement means that the nebulizersystem does not need to be adjusted when the motor vehicle is operating,whatever its dynamic.

According to a specific embodiment of the invention, the inclined bottomface 60 comprises a protrusion 74 arranged at one end of the inclinedbottom face 60, referred to as the bottom end.

The protrusion 74 is suitable for being secured, by any servo controlmeans known to a person skilled in the art, to at least one element ofthe hydraulic circuit of the nebulizer system 10, such as a pump, forexample.

The protrusion 74 comprises a first protuberance 76 that has a mainextension axis substantially parallel to a face of the tank for theliquid 12 referred to as the side face and is capable of being secured,by any servo control means known to a person skilled in the art, to adrain pump (or valve) 54 of the hydraulic circuit of the nebulizersystem 10.

One embodiment proposes that a suction strainer 75 is provided at theinterface of the protrusion 74 and the first protuberance 76. Thepurpose of this suction strainer is to stop possible particlescirculating in the hydraulic circuit of the nebulizer system 10. Thesuction strainer can, for example, comprise pores with a size of between10 and 30 μm, and preferably 20 μm.

The protrusion 74 further comprises a second protuberance 81 that has amain extension axis substantially parallel to the opposing top face 62of the tank 12 for the liquid and is capable of being secured, by anyservo control means known to a person skilled in the art, to a pump 56for moving the liquid of the hydraulic circuit of the nebulizer system10.

In the embodiments shown, the protrusion 74 is arranged, in thisinstance, for example in a substantially central manner, on the width ofthe inclined bottom face 60, in such a way as to create two clearances79 to either side of this protrusion 74.

Preferably, the filter system 16 is arranged opposite and/or in thecontinuation of the protrusion 74.

Such an arrangement is advantageous in that two clearances 79 are thuscreated. The two clearances 79 each form a passage in which it ispossible to arrange other elements of the motor vehicle such as, forexample, air pipes.

In a specific embodiment, the tank 12 for the liquid is produced in atleast two parts, one of which forms a cover 68 and comprises at leastone positioning means 66 for the nebulizer enclosure 14.

In this instance, the cover 68 corresponds to the opposing top face 62and extends in a substantially horizontal plane.

The positioning means 66 for the nebulizer enclosure 14 can be producedin the form of a cylindrical barrel comprising an opening in its centralpart capable of receiving a complementary means arranged opposite on thenebulizer enclosure 14.

One specific embodiment proposes that the positioning means 66 isprovided with reinforcing ribs in order to support the weight of thenebulizer enclosure 14.

In another specific embodiment, the tank 12 for the liquid and, inparticular, the cover 68, comprises a plate 78 provided with openingsfor electrical connectors to pass through.

In yet another specific embodiment, the tank 12 for the liquid and, inparticular, the cover 68, comprises a support means 70 for the nebulizerenclosure 14 and, in particular, the nebulizer tube 18 part of thelatter.

The tank 12 for the liquid further comprises an indentation 72 allowingthe air inlet module 26 of the nebulizer system 10 to be at leastpartially accommodated.

The nebulizer system 10 comprises a priming circuit 80 provided with abypass valve 82.

In one embodiment, the priming circuit 80 is positioned between the pump56 for moving the liquid and the tank 12 for the liquid. It makes itpossible, when the nebulizer system 10 is in the priming mode, to primethe pump 56 for moving the liquid before forcing the mist into thepassenger compartment. Indeed, after a certain amount of time withoutuse, the pump can lose pressure and no longer be able to functioncorrectly. Such a characteristic has an impact on the droplets formedand therefore, ultimately, on user comfort. The priming circuit 80 helpsovercome this disadvantage by restoring the operating pressure of thepump 56 for moving the liquid before injecting the droplets into thepassenger compartment.

The nebulizer system 10 also comprises a transfer circuit 84 fortransferring the liquid from the tank 12 for the liquid to the nebulizernozzle 22.

The circuit for transferring the liquid is made up of a main circuitbetween the tank 12 for the liquid and the nebulizer nozzle 22 and adrain circuit comprising, in this instance, a draining member 54.

The draining member 54 can, for example, be a two-way valve allowing thehydraulic circuit of the nebulizer system 10 to be closed or opened.

The drain circuit allows water to be discharged from the nebulizersystem 10. The draining takes place by force of gravity, for exampleperiodically and preferably every month or periodically in the eventthat the liquid in the nebulizer system 10 freezes.

As described previously, the nebulizer system 10 also comprises a pump56 for moving the liquid.

In the embodiments shown, the pump 56 for moving the liquid isfluidically connected to the tank 12 for the liquid, by means of achannel.

The tank 12 for the liquid is interposed at least partially between thenebulizer enclosure 14 and the filter system 16.

In this instance, the tank 12 for the liquid is interposed spatiallybetween the nebulizer enclosure 14 and the filter system 16.

Such a spatial arrangement helps reduce the space requirement of thenebulizer system according to the present invention.

Moreover, the present invention allows a submerged filter system, i.e. asystem below the level of the liquid of the tank, for the latter, whichfacilitates the priming of the nebulizer system when it is switched on.

The filter system 16 comprises at least one filter provided with amembrane provided with pores smaller than 50 μm, and preferably smallerthan 20 μm.

The filter system 16 can, for example, comprise two or more filtersdepending on both the desired level of purification and the origin ofthe water.

In this instance, the filter system comprises a substantiallycylindrical casing. Other embodiments propose a rectangular or squarefilter.

The filter system 16 is positioned upstream from the nebulizer nozzle 22generating the mist and downstream from the pump 56 for moving theliquid, relative to the direction of flow of the liquid to be nebulizedin the circuit.

The filter system 16 ensures that the nebulized liquid and, inparticular, the water nebulized in the mist, is healthy for the users ofthe vehicle. This is especially important when the diameter of thedroplets is smaller than 10 μm, in which case they reach as far as thelungs of the users of the vehicle.

The nebulizer system 10 can also comprise a water softener for reducingthe hardness of the water in a known manner by reducing the quantity ofcalcium, thus increasing the service life of the system.

The water softener can, for example, be installed in the tank 12 for theliquid to be nebulized.

The nebulizer system 10 can comprise electronic command and controlequipment such as sensors, actuators, and/or a human/machine interface.

The nebulizer system 10 can be integrated into a motor vehicle, forexample into a central console as partially shown in FIG. 1 . Inparticular, the nebulizer system 10 can be arranged in a housingsituated above and/or between rear air ducts and below the front seatarmrests.
